Specification forming part of 'Letters Patent 0. 194,018, dated August 7, 1877 "applicationfiled I June 16, 1877.

To altwhom it may concern:

Be it known that I, OHARLEs P. S. WARD- WELL, of Lake Village, in the county of Belknap and State of New Hampshire, have invented an Improved Corn-Sheller; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings making part of this specification.

Figure 1 is a side view of the corn-sheller; Fig. 2, a top view thereof; Fig. 3, a side view of the shelling-wheel; Fig. 4, an edge view thereof; Fig. 5, a view of the inner surface of the hopper-concave.

Like letters designate corresponding parts in all of the figures.

My improvements are upon that class of corn-shellers in which a shelling-wheel revolves inside of a case and'co-operates with a movable counterpressing concave or hopper, to perform the function of shelling the corn.

The shellingwheel A revolves inside of the caseB, which forms part of the stand of the machine, and incloses the front side of the rim and flange part of the wheel, the back side of the wheel being in one plane and smooth and simply flush with the rear edge of thecase, and consequently needing no inclosing.

The shaft a of the wheel turns in an extended central bearing, b, of the case, and has a pinion, c, on its front end, into which a driving-wheel, 0, gears, the said driving-wheel being mounted on a fixed pivot, d, and provided with a crank-pin or handle, f, or other means of communicating motion to it. Thus the shelling-rim g and flange h of the shellingwheel A are gboth given a rapidmotion, and are caused to turn downward on the side of the machine next to the position where the operator stands, and these functional parts being near the periphery of the wheel, the rapidity of their motion is efiective for rapid shelling.

My invention .relates principally to the construction of these functional parts, the shelling-rim g and feeding-flange h, and of the counter-pressure hopper or concave D, operating in connection therewith.

Upon the periphery or face of the shellingrim g, which projects at nearly right angles from the wheel, is a set of ribs or teeth, i i,

grains, removes them with ease.

The flange h of the shelling-wheel, which projects beyond the shellingrim g in the direction of the face of the wheel, also has teeth k k thereon, arranged obliquely, as shown, or otherwise. the ears of corn down in the concave, and also assist in the shelling. Their form is more pointed than the shelling-teeth i z.

The shelling-rim and feeding-flange of the shelling-wheel form a nearly right-angled corner, in which the ears of corn are held by the counter-pressure concave D, as shown most clearly in Fig. 2. This concave, mounted near its'upper end on pivots l l, swings obliquely inward in relation to both the shelling-rim and feeding-flange of the shelling-wheel, or toward the said right-angled corner formed thereby. I find that this arrangement produces the best result, thus dividing the pressure between the shelling-surface and the feeding-surface, one regulating the other thereby. The concave has a few oblique teeth or cross-ribs, m, at the lower end, to afford the proper resistance to the descent of the ears and insure their complete shelling. The inward pressure of this concave to press the ears of corn against the shelling wheel is produced by a counterweight, consisting, as represented in the drawings, of a weighted arm, E, projecting outward therefrom. The advantage of this weight over a spring in this place is, that its action is the same on small cars and large ears of corn, as required, whereas a spring is much more powerful in action with large ears than with small ones.

Below the lower end of the concave, the

case B forms an inclosed passage, n, to conduct the shelled corn and cobs downward to a receiver.

What I claim as my invention, and desire to secure by Letters Patent, isu 1. In a corn-sheller,ashelling-Wheel,A,con-

These teeth serve mainly to feed structed with a peripheral shelling'rim, g, and

a feeding-flange, h, projecting outward nearly atright angles from one edge of the shellingrim, both the rim and flange having teeth or projections on their faces, substantially as and for the purpose herein specified.

2. In a corn-sheller,ashelling-wheel,A,constructed with a peripheralshelling-rim,g,having teeth or ribs 2' 6 upon its periphery, arranged in lines oblique to the axis of the shelling-wheel, and an outwardly-projectin g toothed feeding-flange, substantially as andfor the purpose herein specified.

3. In combination with the shelling-rim g and feeding-flange h, arranged at an angle to CHAS. P. s; WARDWELLQ Witnesses: i
